1 Running Tank Maintenance
Test results above limit = high concentration of primarily organic nutrients. Denotes the risk or proves the reason of unwanted algae and cyanos growth. Regular DOM testing allows to make all necessary measures, avoiding further DOM concentration increase and consequently the increase of nitrates, phosphates and other unwanted matter level:
- Lowering of food dosage
- Lowering of DOM-based additives dosage
If test results are not above limit and yet the algae and cyanos grow in the tank, the problem is most probably in high concentration of inorganic nutrients trace elements for instance.
2 Use of active carbon
Used for determination of active carbon quality or its proper way of application (amount, time), perhaps even for the comparison of various brands. Start the 1st test just before the application of carbon, the 2nd one ca. 4 hours after. However the DOM has to be present in water in measurable concentration before the 1st test otherwise any probing makes no sense.
With certain limitations CS TEST Organics is also usable when checking the efficiency or settings of skimmers. Skimming removes from water not only DOM, but also POM (particulate organic matter), which is however detectable by the test only partially. Nevertheless, the results of testing treated as a good estimation are well usable in practice.
Start the 1st test just before the change of settings or exchange of skimmer, the 2nd one ca. 15 20 hours after. As in the previous case, the DOM has to be present in water in measurable concentration before the 1st test.
